We postulate that these mode dwelling results partially explain why, during the rotation task, touch rotate and wand performed similarly both in terms of completion time and accuracy.
For instance, Shepard and Metzler (1971) demonstrated that response latencies in a mental rotation task varied as a linear function of rotational angle between the target and comparison object.
For the external and internal rotation task, the chair was in the neutral position with the dynamometer rotated 20° and 50° tilted.
The mental rotation task alone also activated 37 voxels, mostly in parietal regions.
More radically, some have doubted whether the rotation task really involves imagery at all (Marks, 1999).
Following the briefing, participants were asked to perform both the movement task and the rotation task.
Participants always completed the movement task prior to the rotation task.
They always completed the movement task followed by the rotation task.
The data from the rotation task was subjected to a repeated measures ANOVA test.
The single within-subjects independent variable for the rotation task was rotation technique.
The dependent variables for the rotation task were rotation time (RT), measured in seconds.
